The bicycle pump is an essential accessory for cyclists, athletic and otherwise.
Bike pump function is to increase the internal pressure of the wheels and, more specifically, of the air chamber (normal or tubular); usually, the same cannot be done for tubless, most tenacious of the traditional system, as they need more pressure to “heel” at the time of installation.
The bike pump is a hand tool (or electric or gas) structured by a cylinder in which a piston with membrane (estate), and from a terminal of no return; This is directly connected to the piston or is equipped with a connector (tube) rubber.
Pushing the piston up to the stop, the air inside the cylinder is compressed and forced to pass through the terminal; Instead, pulling it upwards, this creates a vacuum that draws in outside air by an operculum, instead sealed when pushed. By connecting the terminal to the valve of the inner tube, the latter is inflated.
By bike pump there are various types, which differ in:
To make a short summary, like bike counter defined on EZINESPORTS.COM, bicycle pump types include
- Hand pumps
- Foot pumps
- Floor pumps
- Electric pumps
- CO2 canisters.
Of these, some are transportable, also known as “emergency”, while others are a working tool.
NB. We omit purposely suspension pumps, which have a different application.
Recall that in the various disciplines of cycling you must comply with different technical characteristics. Among these, is also very important the pressure of tires, which in the race bike get to 9 bar. Cheapest pumps are unable to reach these levels.
In addition, the amount of air forced into each pumped varies depending on the capacity of the cylinder. The more spacious, less pump strokes are applied; This will reduce both the effort and the overall time (very important if the surgery is performed during a competition).
The bicycle pump is high stress tool; in fact, it must not only withstand stress mechanical hydraulic inflation but also that of the rider often “in a hurry”. For this reason it is important that it is pretty solid.
One of the aftermarket bicycle pump, now almost indispensable in cycling sports, is the gauge. This measuring instrument is necessary to verify the pressure inside the tube, azzeccandola perfectly and avoiding “approximations”.
It is logical to assume that the various types of bicycle pump may have different prices. Quality is a rather important and discriminant, for those who decide to set cycling sportive, is absolutely essential.
A bicycle pump to low range costs about 1.5 -2 €, whereas a high foot, which could inflate even tubles (including those from motorcycle and car) reaches 280 €.
